While on break yesterday, I stretched out on the sofa. A light breeze blew in through the window (yes, it was open at the time), the sun shone - and then I heard a squirrel make a noise the likes of which I have never heard any squirrel make before - any animal make before, for that matter.
Drawing on my skills as a liberal arts major, I looked out the window. The squirrel in question had tensed every muscle and devoted its whole body to this sound. Seconds later, a second squirrel dashed across the yard, praying that it would make its tree. Hot on the tail of the second squirrel? A hawk.
Sam barreled out the door, full speed, full defense bark, full alert and the hawk decided to go elsewhere for lunch.
Probably Sam had chosen to protect me, but I prefer to think that he charged out to protect his squirrels.
